Helicopter-borne Radiometrics (HRD) Area 138 Nordenham

BGR conducted within the project „Airborne geophysical surveys for mapping the shallow subsurface in Germany “ (D-AERO) airborne surveys at the German North Sea coast.The survey area Nordenham (2009/10) is bounded by the Jade Bight to the west and by the river Weser to the east. The size of the area is about 368 km². The area was surveyed with 12 flights totalling to 1562 line-km (43,577 survey points). The nominal separation of the 97 ESE-WNW lines and 11 NNE-SSW tie lines was 250 m and 2000 m, respectively. The maps display the total count, the (equivalent) content of potassium, uranium and thorium as well as the exposure rate at ground.
